Application July 24, 1945, Serial No. 606,864

1 Claim. 1

This invention relates to equipment for fire engine houses and more particularly a scrubbing machine for fire hose.

One of the objects of this invention resides in the provision of mechanical means whereby fire hose employed at a fire will be quickly cleaned and returned tostorage in the hose truck for further use.

Another object of this invention resides in the particular association of the brush and adjacent guide roller.

With these and other objects in view, this invention resides in certain novel features of construction and arrangement of elements to be hereinafter more particularly set forth in the specification, illustrated in the accompanying drawings and pointed out in the appended claims and, While this disclosure depicts our present conception of the invention, the right is reserved to resort to such changes in construction and arrangement of elements as come within the spirit of the invention.

In the accompanying drawings forming a part of this application;

Fig. 1 is a side view of a fire hose scrubbing machine as constructed in accordance with this invention.

Fig. 2 is a plan view thereof.

Fig. 3 is a longitudinal vertical sectional view taken approximately on line 33 of Fig. 2.

Fig. 4 is a cross sectional view taken approximately on line 4-4 of Fig. 2.

In the present illustration of this invention the numeral 5 designates, in general, a fire hose scrubbing machine consisting of an elongated trough 6 supported by legs I and preferably braced or reinforced by suitable beams 8 connected to and extending between the legs I.

Journalled in bearings 9 adjacent opposite ends of the trough and extending thereacross with certain portions thereof disposed above the upper edge thereof is a feed guide roller l and a discharge guide roller ll over which a fire hose, to be scrubbed, is drawn by the machine attendants. Also rotatably mounted in bearings l2, closer to the feed guide roller l0 than to the discharge guide roller II, is a brush l3 having one end of its axle l4 extending outwardly of one side of the trough and provided with a pulley I connected to a pulley l6 of a motor ll, mounted on the side of the trough, through the instrumen- 2 tality of a belt l8 and, although said power transmitting means is herein shown in the form of V-shape pulleys accommodating a similarly shaped belt, it is to be understood any conventional means may be employed to rotate the brush.

Adjacent the brush I3, on the discharge side thereof and a predetermined distance below the upper edge of the trough, is a tension guide roller 20 over which the hose is trained subsequent to being disposed under the brush.

Disposed over the brush is a suitably shaped splash guard 2| to the rear end of which is hingedly connected a cover plate 22 adapted to prevent splashing of the washing fluid from the trough as the hose is drawn under the brush and over the tension guide roller.

In order to scrub a fire hose with a machine of the aforesaid construction, it is trained over the feed guide roller and under the brush, then over the tension guide roller onto the discharge guide roller, whereupon, the motor is started and thus causes the brush to rotate through the washing fluid and against the hose as it is fed at one end of the trough by an attendant and led therefrom by another attendant stationed at the discharge end of the trough, the latter mentioned attendant regulates the tension of the hose under the brush by pulling it against the tension guide roller and thereby subjects it to such frictional contact with the bristles of the brush as will remove dirt and other foreign matter collected thereon while used at a fire.

With this invention fully described, it is manifest that a fire hose Washing machine is provided whereby the hose is quickly cleaned and restored to the hose truck and, through the simplicity of construction thereof, it can be manufactured at a small cost and operated by unskilled labor.

Having thus described our invention, what we claim and desire to protect by Letters Patent is:

A fire hose washing machine comprising, an elongated trough supported on legs, a feed guide roller j ournalled at one end of the trough with a portion thereof disposed above the upper edge of the trough, a rotatable brush journalled on the upper edge of the trough closer to the feed end than to the discharge end thereof and having its lower portion submerged in a washing fluid within the trough and its remaining portion disposed outwardly of the trough, power transmitting means connected to the rotatable brush, a tension guide roller journalled within the trough in close proximity to the discharge side of the brush with its upper portion disposed above the lowermost portion of the brush, a discharge guide roller journalled on that end of the trough opposite the feed end thereof and having its upper portion disposed above the edge of the trough and upper portion of the tension roller, a splash guard disposed over the brush and tension roller, and a rearwardly extending rectangular cover plate hinged to the rear side of the splash guard and lying over the trough and tension guide roller.
